IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 128,366, dated June 25,1872.

To all whom it may concern:

Be it known that I, GENERAL DAvrs, of Mumford, in the county ofTalladega and in the State of Alabama, have invented certain new anduseful Improvements in Seed-Sower; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangementof a combined cultivator, seed-dropper, and fertilizer-distributer, aswill be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side view, and Fig. 3 a rear elevation of my machine. Fig.2 is a plan view of the hopper with the frame holding the same, andFigs. 4 to 7 are detached views of various parts of the machine.

The frame of my machine consists of the beam A, with foot B attached andsuitably braced to it. The foot B extends a suitable distance above thebeam, and through its upper end passes a cross-bar, O. D D are thehandles of the cultivator, attached to the beam A, and, passing upward,are connected with the ends of the cross-bar G, and still further towardthe rear with another cross-bar, 0, running parallel with the former.The two cross-bars O G, with the parts of the handles between them, forma square frame for the reception of the hopper, and from the rearcross-bar O a post or column, E, extends downward, its lower end beingsecured to or in a stirrup, a, attached to the foot B. G represents theplow attached to the lower end of the foot B by means of a clamp, b,consisting of two angular or L-shaped pieces attached to the plow andfastened together on the rear side of the foot by a pin, as shown inFig. 3. On the rear side of the foot B is secured a steel plate, H, andin the foot is made a recess covered by said plate, thus forming, as itwere, a mortise in which a roller, 0, on the inner end of a stirrup, d,is allowed to slide up and down. The lower end of the foot B is hollow,and through the' same is passed a tube, I, which extends upward in rearof the foot as high as the stirrup a. J represents the hopper attachedto a hollow headblock, K, and passed down between the crossbars 0 O, thelower end of the head-block passing down through the stirrups a and d.On the inner sides of the cross-bars O O are rollers f f, and at theouter end of the stirrup a a roller, 6, to allay any friction of thehopper and head-block when the machine is in motion. In the head-block Kis attached a pipe, 1, which, when the head-block is placed in position,enters the pipe I, this pipe passing into the head-block on the outsideof the pipe I, the two together forming a conductor to deposit the seedin rear of the plow G. The upper end of the pipe I joins an opening, g,in a hoop or drum, L, placed in a circular mortise in the head-block,and provided with'another opening, 9, through which the seed falls fromthe hopper onto a revolving drum, M, within said hoop, the seed beingtaken by said revolving drum and carried to the opening y, when it dropsthrough the tubes I 1 into the ground in rear of the plow G. The hoop Lis attached to a plate, L, on one side, and closed by a similar plate onthe other side, said plates being fastened on, the sides of thehead-block by screws. The drum M, inside of the hoop L, is attached to ahollow cylinder, h, which passes through the centers of the plates L L.This drum is, on its circumference, provided with five bucket-valves, kk, which open inward, and when closed complete the outer circumferenceof the drum. Inside of the drum M, and loosely upon the cylinder h, isplaced a collar, m, having five arms, a n, which operate in loops on theunder or inner sides of the bucket-valves k is. Through the hollowcylinder h passes a shaft, 19, having a pin, i, which passes through aslot in the cylinder and into a notch on the inside of the collar m, sothat by turning said shaft the collar will be turned to set the valves,and thereby regulate the amount of seed to be dropped in each hill. Theshaft 12 is provided with a head on one end and a nut on the other, sothatit may be fastened and held rigid when the valves have been set asdesired. Upon one end of the cylinder is secured a five-prongedskip-wheel, N, into which operates a wedgeshaped sprin g-skip, O, forapurpose that will be hereinafter set forth. On the other end of thecylinder is a fivepointed star-wheel, P, which is operated by cog-valves1" r on one of the drivin g-wheels It. The driving-wheels are placedupon an axle passing through the rear end of the stirrup d. On the innerside of one of these wheels is formed a smaller wheel, 8, having on itscircumference the four cogs 1' r,'which I call cog-valves, as they canbe turned down so as not to operate upon the wheel P.

It will be observed that th ere are five buckets in the drum M, fivepoints in the skip-wheel N, and five points or cogs in the star-wheel P,and that they are all attached to the hollow cylinder h and revolvetogether. The starwheel P operates by being moved forward something overone-tenth part of a revolution.

- The skip 0, having its spring properly arranged to press upon the armof the skip, operates upon the skip-wheel N and causes the other portionof the fifth part of the revolution, and is further so arranged that oneof the buckets 70 will be directly over the opening 9 or mouth of thepipe I.

The distance or space between the hills planted or dropped is obtainedby means of the cog-valves r r on the driving-wheel. One cog beingraised gives one motion to the starwheel 1?, which is completed by theskip O and skip-wheel N. Two cogs opposite each other being up decreasesthe distance one-half. All four cogs being raised, decreases toonefourth, the size of the driving-wheels governing the space ordistance.

The wheels R R are made of wood with suitable iron tires, and havesmaller wheels 9 on their inner sides. To the inside of this is attacheda metal wheel, t, with collar attached, which collar passes through thewooden wheels forming the hubs for the same.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The plate H, stirrup cl, and roller 0, constructed and arranged onthe foot B, in combination with the head-block K, substantially asherein set forth.

2. The arrangement of the rollers e and ff, in combination with theframe B, D, E, and stirrup a, so as to allay the friction of the hopperwhen in motion, substantially as herein set forth.

3. The skip-wheel N, attached on the hollow cylinder h and operating incombination with the spring-skip O, substantially as and for thepurposes herein set forth.

4. The combination of the wheel R with cogvalves 1", star-wheel P,hollow cylinder h, shaft 19, drum M, with valves, and the skip-wheel Nand spring-skip 0, all constructed and operating substantially as setforth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 28th day of September, 1871.
